abstract = {The release of alkali metals (K, Na) and non-metals (S, Cl)
during a Calcium Looping (CaL) Gasification Process of waste
derived-hydrochars, water-leached samples and CaO-biomass
blends was investigated. Special attention was paid to
biomasses that are not particularly promising for
gasification requirements but have a large occurrence in
Europe, including Grape Bagasse, Organic Fraction of
Municipal Solid Waste (OFMSW), Green Waste, and Out-of-use
woods from construction debris and discarded furniture. The
release experiments were performed at 650 °C in a flow
channel reactor to investigate the behavior of inorganic
trace substances. Hot-gas analysis was performed by
Molecular Beam Mass Spectrometry (MBMS). Thermodynamic
equilibrium calculations via FactSage indicate H2S, carbonyl
sulfide (COS), KCl, NaCl, and HCl as the main inorganic
impurities. Thus, the focus of the experiments was placed on
these species. It was found that the concentrations of trace
elements released during gasification at 650 °C, such as
H2S, SO2, KCl, or NaCl, are hardly affected by intense
water-leaching. In contrast, carbonaceous materials from
hydrothermal carbonization exhibit a higher concentration of
potassium trace substances (K, KCl, and K2Cl+). When biomass
samples are combined with CaO, the total amount of inorganic
trace compounds (K-, Na-, and S-compounds) in the resulting
syngas could be decreased.},
